Description

Technical Field

[0001] The utility model relates to the technical field of a CPVC cable protection tube reinforcement device, and more particularly to a CPVC cable protection tube reinforcement device. Background Art

[0002] In existing cable protection tube reinforcement technology, the structural design of the protection tube connection part is often too simple, which leads to insufficient protection of the internal cables. This insufficient protection may make the cables vulnerable to damage underground or in other harsh environments. For example, due to underground pressure, external force impact or environmental factors (such as moisture, soil, chemicals, etc.), the cables may deform, crack or corrode, which will not only affect the normal operation of the cables, but also shorten the service life of the cables and increase the frequency of repairs and replacements, thereby bringing additional maintenance costs and inconvenience.

[0003] In addition, the installation operation of the protective tube connection in the prior art is usually cumbersome. This may be because the design of the connection part is not reasonable enough, resulting in more steps and tools required during the installation process. This cumbersome installation operation not only prolongs the installation time and increases labor intensity, but may also increase the risk of installation errors, thereby affecting the overall performance and reliability of the cable system.

[0004] In addition, some devices have appeared in the prior art that are designed to achieve rapid docking of protective tubes, but the structures of these devices are usually simple and cannot be quickly disassembled or even cannot be disassembled. This means that when the protective tube needs to be maintained or replaced, the operator may need to spend a lot of time and energy to disassemble and reinstall the protective tube, which not only reduces work efficiency, but may also cause unnecessary interference and damage to the cable system.

[0040] A mounting groove 24 is formed on the outer side of the protection tube 1 , and a gasket 25 is provided in the mounting groove 24 .

[0041] More specifically, when the device needs to be used, the protective tubes 1 are first respectively put on the outside of the cables, and then the plug 22 connected to one end of one of the protective tubes 1 is inserted into the slot 23 opened at the other end of the other protective tube 1, and then the gasket 25 is installed into the installation groove 24, and then the clamping rings 21 set on the inner sides of the two connecting sleeves 2 are inserted into the card groove 20 opened on the outside of the protective tube 1, and the two connecting sleeves 2 are spliced ​​together through the mounting plate 3 set on the outside, thereby achieving protection of the cable.

[0042] In summary, when the entire device is in use or running: when it is necessary to maintain or replace the connection of the protective tube 1 or the connecting sleeve 2, first rotate the rotating sleeve 12, the rotating sleeve 12 drives the driving wheel 13 set on one side to rotate, and then the driving wheel 13 drives each driven wheel 11 engaged with it to rotate, and then the driven wheel 11 drives the screw 10 to rotate, and then the matching sleeve 9 will slide along the screw 10, and then the outer side of the matching rod 15 will lose the limit of the matching sleeve 9, and then rotate the quick-lock rod 5 in the corresponding direction, because the edge of the matching groove 16 and the end of the matching rod 15 are both rounded structure designs, and the connecting spring 1 4 only provides a small reset force, and then the side wall of the matching groove 16 squeezes the end of the matching rod 15, so that one end of the matching rod 15 slides out of the matching groove 16, and at the same time, the other end of the matching rod 15 drives the connecting spring 14 to stretch, and at the same time, the quick-clamping rod 5 drives the quick-clamping block 6 to move in the annular groove 7. When one side of the quick-clamping block 6 and the other side of the fixed block 18 are in contact, the position of the quick-clamping block 6 corresponds to the position of the straight groove 8, and then the quick-clamping sleeve 4 and the quick-clamping rod 5 are pulled to both sides, and the quick-clamping rod 5 can be removed from the quick-clamping sleeve 4. At the same time, one end of the matching rod 15 loses its limit, and the connecting spring 14 drives the matching rod 15 to reset, and then The connecting sleeve 2 is opened for maintenance and replacement. After the maintenance and replacement is completed, the quick-clamp rod 5 is re-passed through the mounting plate 3, and the quick-clamp sleeve 4 is sleeved to the outside of the quick-clamp rod 5 from the other side.
